This paper presents a voltage changer optimized to multiply or to divide the input voltage by an integer factor of 2, 3,4,..., with a very high efficiency. The paper first introduces a review of the quasi-continuous current transformer converter in a step by step fashion.The last step presents the full bidirectional zero voltage switching (ZVS) converter. The theoretical study demonstrates the way to achieve ZVS operation by only decreasing the value of the transformer magnetizing inductance. ZVS conditions (developed in the paper) lead to an interesting way to control the converter, and a discrete variable frequency control is proposed. Allowing triangular current in the transformer leads to ZVS in the expanse of higher root-mean-square (RMS) current. The evaluation of the current is also carried out in the theoretical study.An experimen- tal implementation shows an efficiency higher than 97.5% and confirms the accuracy of the theoretical study.

提出了一种优化变压器,它可将输入电压用整数因数2、3、4进行乘、除,具有很高的性能。逐步介绍了准连续电流型变压变流器,最后介绍了全双向零电压开关(ZVS)变流器。理论研究表明,只要降低变压器磁化电感的值便可实现ZVS工作。ZVS工作条件产生了有利的变流器控制方法,并提出了一种离散变频控制方法。变压器中允许有三角形电流使ZVS具有较高的电流有效值。对电流的估算进行了理论研究。实验结果显示其效率高于97.5%,并证实了理论研究的精确性。
